Re: Custom gallery poses in tray reset to default, but not uploaded gallery vers.
@Lightsims8 I've had no reports that custom poses broke with the patch. I have seen reports that new Gallery uploads don't all show poses anymore (which would be desired Gallery behaviour for non-CC uploads).
That said, are you using anything like OneDrive that might interfere with your files and settings? It's worth checking your antivirus as well, as it can affect what information is saved in your user folder. Here are a couple of threads with info:

Beyond that, I'd suggest getting support for Pose Player (and poses) from Andrew's site.
